Embryonic stem cell factors DPPA2/4 amplify active H3K4me3-H2AK119ub chromatin domains in non-small cell lung cancerGenes & development · 2026
Summary (written by the submitters)
Embryonic regulators are often re-expressed in cancers, however the functional and molecular significance of this is not always understood. The epigenetic priming factors Developmental Pluripotency Associated 2 and 4 (DPPA2/4) have crucial roles in early development and are implicated in cancer pathogenesis. We reveal in non-small cell lung cancer (NSCLC), DPPA2/4 co-expression is associated with poorly differentiated tumours and impaired patient outcomes.

Biochemically, human DPPA2/4 multimerise for their protein stability and enhanced nucleosome binding activity. In NSCLC cells, DPPA2/4 bind CG-rich sequences including promoters of developmental, Wnt signaling and catabolic genes. Chromatin state modelling revealed DPPA2/4 preferentially bind active H3K4me3 and H3K27ac domains that were intriguingly also enriched for PRC1 and its product H2AK119ub, validated by H3K4me3-H2AK119ub sequential ChIP. Knockdown experiments revealed DPPA2/4 were required to maintain RING1B and H2AK119ub at these domains. Surprisingly, despite the presence of PRC2.1, these regions lacked any detectable H3K27me3, suggesting an uncoupling between the recruitment of PRC2 to chromatin and its catalytic product. When exogenously over-expressed in NSCLC cells where they are not normally present, DPPA2/4 bind to and promote active chromatin states, resulting in an increase in vivo xenograft tumour growth. Our results demonstrate how in NSCLC cells, DPPA2/4 act as molecular amplifiers of active and poised chromatin. Together, this highlights how aberrant re-activation of embryonic factors in cancers may take on new functions, promoting tumourigenesis.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE310144_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

Raw reads on ENA ↗

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1365196 and SRA study SRP645397. Searching any of these in the dataset finder brings you back here.
